肠缺血/再灌注致肺损伤时肺内HO-1/CO与iNOS/NO相互作用的研究

目的观察肠缺血/再灌注(I/R)致肺损伤时肺内HO-1/CO与iNOS/NO的相互作用。方法采用肠缺血/再灌注模型。32只Wistar大鼠随机分为假手术组(Sham组)、肠缺血1 h再灌注6 h组(I/R组)、氨基胍组(AG组)和血晶素组(hemin组)。检测肺组织中HO-1和iNOS的表达,观察肺组织丙二醛(MDA)、血清一氧化氮(NO)及动脉血中氧血红蛋白(Hb-CO)的含量,同时观察肺组织病理形态学改变。结果与Sham组比较,I/R组HO-1和iNOS表达显著增强(均P<0.01);AG组HO-1和iNOS表达较I/R组明显降低(均P<0.05);Hemin组iNOS表达较I/R组明显降低而HO-1表达明显升高(均P<0.05);I/R组肺组织MDA、血清NO、血中HbCO较Sham组显著增加(P<0.05或P<0.01);与I/R组比较,AG组、Hemin组肺组织MDA、血清NO显著降低(P<0.05或P<0.01)。AG组的HbCO明显降低而Hemin组的HbCO明显升高(P<0.05)。病理学检查显示,AG组与Hemin组肺组织损伤程度较I/R组明显减轻。结论NO及CO对肠I/R肺组织具有保护作用,两者之间存在着相互作用,肺内HO-1/CO的大量生成具有使NO产生减少的作用,同时iNOS/NO的过量生成具有上调HO-1表达使CO产生增多的作用。     

Action of intravenously administered talipexole on the rat striatal neurons receiving excitatory input from nigral dopamine neurons

Electrophysiological studies using rats anesthetized with chloral hydrate were performed to elucidate whether or not intravenously injected talipexole acted as a D₂ receptor agonist on the striatal neurons in comparison with the action of bromocriptine. The activities of the striatal neurons were extracellularly recorded using a glass microelectrode attached along a seven-barreled micropipette, each barrel of which was filled with talipexole, bromocriptine, SCH23390 (D₁ antagonist), domperidone (D₂ antagonist), glutamate or 2 M NaCl. These drugs were iontophoretically applied to the immediate vicinity of the target neuron being recorded. The effects of talipexole and bromocriptine were examined on the neurons, whose spikes (induced by the stimulation of the substantia nigra pars compacta) were inhibited by the iontophoretic application of domperidone. Iontophoretic application of talipexole or bromocriptine increased spontaneous firing of these neurons and this increase in firing was also inhibited by iontophoretically applied domperidone. In the same neurons, intravenously administered talipexole (0.01, 0.02 and 0.04 mg/kg) dose-dependently increased firing, and this increase was inhibited by microiontophoretically applied domperidone, but not by SCH23390. On the other hand, the intravenous injection of bromocriptine (0.1, 0.2 and 0.4 mg/kg) also increased the firing rate. However, the increase was not dose-dependent and fluctuated; the firing transiently decreased during the increase in firing with intravenously administered bromocriptine. However, the bromocriptine-induced increase in firing was also suppressed by domperidone, and decrease in firing was inhibited by SCH23390. These findings suggest that talipexole acts as a D₂ agonist on the striatal neurons receiving input from substantia nigra pars compacta and increases firing when intravenously applied. However, intravenously administered bromocriptine appears to act as both a D₂ agonist and probably as a D₁ agonist on the striatal neurons to increase and decrease firing, respectively.     

中西医结合治疗慢性肾炎疗效观察及其与血液流变学和微循环的相关意义分析

本文对比观察了中西医结合治疗与单纯西药治疗慢性肾炎的临床疗效,结果表明,前者缓解率及总有效率分别为79.8%和92.1%,显著高于对照组(均P<0.01)。治疗组各临床类型及各中医证型的疗效亦均明显高于对照组相对应的各型肾炎(P<0.05～0.01)。治疗组各型肾炎之血液流变学及甲皱微循环改善均较对照组为显著。两组中完全缓解加基本缓解者,该两类检查指标改善极为显著(P<0.05～0.01),而好转及无效者则无明显改善(P>0.05)。提示临床疗效与之密切相关。     

FRANTZ'S TUMOUR: PAPILLARY AND CYSTIC CARCINOMA OF THE PANCREAS

Frantz's tumour (papillary and cystic tumour) of the pancreas is a rare neoplasm usually seen in young women. It is of low grade malignancy and deserves special note among pancreatic malignancies as it is frequently amenable to local resection and has a good long-term survival rate after excision. Three such cases have been treated at Westmead Hospital, one young male and two females. In two the disease was confined to the pancreas. In one, local invasion outside the pancreas and trans-coelomic spread to the ovaries was present at the time of diagnosis. Complete surgical removal of macroscopic disease was achieved in all three and all remain disease free between 2 and 4 years post-surgery. All have good exocrine and endocrine pancreatic function. These cases are discussed in detail. The need to be aware of this uncommon variant of pancreatic cancer is stressed. Investigation and treatment options are reviewed. The role of cytology studies in diagnosis and the potential for long-term surgical control of this tumour are highlighted on the basis of our limited experience and that presented in recent surgical literature.     

Strecker stent in stenotic hemodialysis Brescia-Cimino arteriovenous fistulas

Flexible tantalum stents (Strecker) were used as an adjunct to percutaneous transluminal angioplasty (PTA) in the treatment of stenotic arterial or venous limbs of Brescia-Cimino hemodialysis fistulas. The diagnostic procedure was performed using retrograde fistulography. After PTA with unsatisfactory results, stents were placed in 5 patients with significant residual stenoses and poor fistula function. Within the mean follow-up period of 6.4 months (range 3–10 months) all fistulas were functioning. We conclude that Strecker stent is useful in the treatment of stenotic hemodialysis arteriovenous fistulas as an adjunct to PTA.

Ethics and Society: Filiation in assisted reproduction: potential conflicts and legal implications

Filiation, or a person's parentage, is one of the major componentsof someone's identity, often with important implications forthat person's welfare in social and personal terms. Fertilityspecialists are enjoined to consider the welfare of the child,and this is a legal requirement in assisted reproduction techniquesin the UK. This paper is in three parts, discussing some ofthe potential problems regarding filiation of the prospectivechild born of assisted reproduction techniques, in relationto the use of gametes and embryos. The first two parts concentrateon the status of children born as a result of treatment givenposthumously, and on filiation problems associated with donationof gametes or embryos, and surrogacy. The third part comparesBritish and French legislation with special regard to the welfareof the child, as well as underlining the common trends and principlesenunciated in both legislations. This is particularly appropriateat a time when the European Society for Human Reproduction andEmbryology is about to issue ethical guidelines in assistedreproduction, and when both the Council of Europe and the EuropeanCommission have commissioned studies on the implications ofthe assisted techniques, including those concerning status ofthe potential children.     

Lifetime and six-month prevalence of mental disorders in the Munich follow-up study

Summary The Lifetime and 6 month DSM-III prevalence rates of mental disorders from an adult general population sample of former West Germany are reported. The most frequent mental disorders (lifetime) from the Munich Follow-up Study were anxiety disorders (13.87%), followed by substance (13.51%) and affective (12.90%) disorders. Within anxiety disorders, simple and social phobia (8.01%) were the most common, followed by agoraphobia (5.47%) and panic disorder (2.39%). Females had about twice the rates of males for affective (18.68% versus 6.42%), anxiety (18.13% versus 9.07%), and somatization disorders (1.60% versus 0.00%); males had about three times the rates of substance disorders (21.23% versus 6.11%) of females. Being widowed and separated/divorced was associated with high rates of major depression. Most disordered subjects had at least two diagnoses (69%). The most frequent comorbidity pattern was anxietyand affective disorders. Simple and social phobia began mostly in childhood or early adolescence, whereas agoraphobia and panic disorder had a later average age of onset. The majority of the cases with both anxiety and depression had depression clearly after the occurrence of anxiety. The DIS-DSM-III findings of our study have been compared with both ICD-9 diagnoses assigned by clinicians independently as well as other epidemiological studies conducted with a comparable methodology.
